 what is a tungsten filament? (with pictures) - info bloom
A tungsten filament is a thin strand of the metal which glows very brightly when an electric current is passed through it. When coiled and sealed inside a glass container filled with an inert gas, a tungsten filament can glow brightly enough to light up a room. It was the inclusion of a tungsten filament in his electrical lighting system that ...

 tungsten filament - tungsten filament products ...
Tungsten filament is used in bulbs, because of tungsten’s properties. The bulb is sealed after removing air from it and filling it with inert gasses under low pressure, thus creating a partial vacuum and a non reactive atmosphere. Tungsten won't react with inert gasses under normal conditions. Thus fusing of the filament is avoided.
